High thermal conductivity / wear-resistant tool steel "FASTCOOL"

Excellent thermal conductivity for rapid cooling. High-strength steel with high wear resistance. A wide variety of stock is readily available.

"FASTCOOL" is a high-speed cooling tool steel developed for hot forming. It achieves an extremely high thermal conductivity of 54 W/m·K, and after heat treatment, it reaches a hardness of approximately HRC 44 to 53, demonstrating excellent material properties. With high wear resistance, "FASTCOOL-50" is suitable for hot stamping, injection molding, and materials for molds, inserts, and tools. "FASTCOOL-55" excels in strength, toughness, wear resistance, seizure resistance, and erosion resistance, making it suitable for tools for hot processing, aluminum die casting molds, and extrusion tools for aluminum and brass, allowing you to choose according to your needs. 【Other Features】 ■ Excellent polishing performance ■ Significantly reduces the frequency of mold maintenance ■ Dramatically decreases the defect rate of complex molded parts ■ Global procurement available, including Europe, America, and Asia Our company has a long-standing track record as a stock trading company, and we strive to deliver the necessary products quickly and reliably to our customers. *For more details, please refer to the materials. We also introduce examples of adopting this steel for runner breakage countermeasures.
